FAQ's of Active Harmonic Filter (AHF):
Q: How does the Active Harmonic Filter improve power quality in industrial systems?
A: The Active Harmonic Filter dynamically compensates for harmonic currents in real time, reducing distortion and unwanted noise in three-phase electrical networks. This enhances equipment efficiency, prolongs their lifespan, and ensures smoother operation in industrial and commercial settings.
Q: What is the installation process for the AHF and where can it be mounted?
A: The AHF can be installed either as a floor-standing unit or wall-mounted, depending on the specific site requirements and available space. The steel enclosure is robust, and all electrical connections are made via terminal blocks for secure and easy setup.
Q: When should I use parallel operation with the Active Harmonic Filter?
A: Parallel operation is recommended when the required harmonic filtering capacity exceeds the rating of a single unit. Multiple AHFs can be connected in parallel, allowing scalability for large or expanding electrical systems in commercial or industrial environments.
Q: What communication interfaces are available for monitoring and control?
A: The AHF supports RS485 Modbus communication out of the box, with Ethernet connectivity available as an option. These interfaces allow seamless integration with facility management and automation systems for remote monitoring and control.
Q: Is the Active Harmonic Filter compatible with generators and UPS systems?
A: Yes, the filter is designed for compatibility with generators, UPS, and various three-phase power supplies, making it ideal for facilities that utilize backup or auxiliary power sources.
Q: What is the noise level and cooling method used in AHF operation?
A: The filter operates at noise levels below 65 dB (measured at one meter), thanks to its force air cooling system. This maintains optimal temperatures within the device, ensuring reliable and quiet operation.
Q: What compliance standards does the AHF meet and what benefits does this offer?
A: The AHF adheres to IEC 61000-6-2, IEC 61000-6-4, and IEEE 519 standards. This ensures international-grade performance and reliability, helping users meet regulatory requirements for power quality and electrical safety.
